I have a PC with an ASUS K8V mobo and two hard drives. One came with it and holds Win XP SP2. Its listed in the bios as Primary Slave. The other is an old one I aded as a backup device and as long as I specify that the primary slave is the first hard drive to boot from I have no problem.
But, I've got a new 1G USB pendrive which, if I forget to take it out before booting up, overides the boot order and either becomes the 1st 'hard drive' to boot from or worse seems to make the backup drive undectable in windows which screws up my overnight backups. I can go into the BIOS and reset the priority but its irritating. Is there a way I can instruct the BIOS to ignore the thing as a boot device (I've tried disabling all removable drives as boot devices to no avail) or format/add something to the pendrive that will have the same effect?
